Felton was allegedly a participant in the notorious Profumo Affair. In 1962, an FBI memo written by J. Edgar Hoover stated that Felton had taken part in sex orgies that involved Christine Keeler, Mandy Rice-Davies, Mariella Novotny, Douglas Fairbanks, Lord Astor, Eugene Ivanov, John Profumo and Stephen Ward. In her autobiography, "The Truth at Last" (2001) Christine Keeler claimed that Felton was working for the CIA. Keeler also claimed that Stephen Ward was providing "confidential information" to Felton.
